I assume you mean having a USB-C port on the side of the watch. Having that port would allow water to get in to the case, the cradle-style charges used by smart watches allow the case to be sealed to prevent water damage. Even if you are careful about not wearing the watch when bathing, or in the rain, or in a pool, its unlikely you remove you watch every time you wash your hands or wash dishes.

Yep, according to the US Flag Code:

When displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag’s own right, that is, to the observer’s left.

TBF, it does have different instructions about how to display the flag outdoors, hard to tell from this perspective if it was actually hung properly.

Even when hanging the flag vertically, this is the correct orientation, with the stars in the upper left.
